Question

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

Answer 1

Step-by-step explanation:

• The perimeter of square is =60m
• Each side of square=perimeter/4
• =60/4
• =15m
• Area of square=side×side
• =15×15
• =225m

By the condition

area of square=area of triangle

• area of triangle =1/2×base×height
• 225=1/2×base×90
• 225×2/90=base
• base=45m
• Base of triangle is 45m
