Question

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

Answer 1

Side of square =60m

Altitude of triangle=90m

So, according to question we have,

=area of square =area of triangle

=60×60 =1/2×b×90

=3600=b×45

=b=80m

Hence, side of the triangle whose corresponding altitude 90 m is 80m.

Answer 2

Answer:

90,8080

Step-by-step explanation:

area of square= area of triangle

60×60 = 1/2×b×h

3600= 1/2×b×90

3600×2= 90b

b =7200/90

b= 80m
