Автор ответа: IVANMENSHCHIKOV

S = a*a
a = 70
S = 70*70 = 4900

IVANMENSHCHIKOV: S = 4900 см^2

Автор ответа: PirkoV

70 умножить на 70=4900 см.

Вика2001354: S = a умножить на b, значит площади квадратного листа картона = 70 умножить на 70 = 7900 сантиметров квадратных

Teen Forums General Chat > Pranks! Monday 2nd 11:31 AM Sarah B Moderator Dave 338 Kate44 Tell us about pranks you played on friends or family members! When I was about nine years old, I bought an enormous plastic spider from a joke shop. It looked very real and had really long legs. I couldn't wait to play a prank on my sister with it. One morning, I put it in the shower just before my big sister went into the bathroom. I waited outside the door. I heard a really loud scream and my sister ran out of the bathroom. I thought it was really funny, but for her it was a terrifying experience! When she found out that I put the spider there, she was really cross and chased me round the house. I feel bad about it now, because I didn't realise just how afraid of spiders my sister is. It took her ages to get over it because she was so shocked! Last February, I sent my brother a Valentine's card. He's quite shy and he didn't have a girlfriend. In the card, I wrote 'Be my Valentine! With love from ???' and I tried to disguise my handwriting. When he opened it, he looked carefully at the writing, and I thought for a moment he realised it was from me. But there was a girl in his class who he liked, and he thought the card was from her. He seemed really pleased about the card. In fact, he decided to ask her out, and now they're going out! Eventually, he mentioned the card to her and she said she didn't send it. He immediately suspected me, so I owned up. He was a bit cross, but he forgave me because of the happy ending.нужно составить по типу такого эссе 50-60 слов любой prank
