Question

plz give me solution step by step fast of question 7

Answer 1

hiii!!!

here's ur answer...

the length of the side of the triangle which contains right angle is the height of the triangle.

therefore height is 42.2m

area of the triangular board = 422.86m²

therefore 1/2×b×h = 422.86m²

=> 1/2×b×42.2 = 422.86m²

=> b×21.1 = 422.86m²

=> b = 422.86/21.1

=> b = 20.04m (approximately)

hence the other side of the triangular board is 20.04m

hope this helps..!
