Question

the area of triangle is equal to that of a square whose each side measures 60 M .find the side of triangle whose corresponding altitude is 90 m

Answer 1

AREA OF SQUARE

= (a)^2

= 60 × 60

= 3600

According to Question

Area of triangle = Area of square  

1 ÷ 2 × b × h = 3600

1 ÷ 2 × b × 90 = 3600

b × 45 = 3600

b = 3600 ÷ 45

b = 80m
