Question

Karl cuts a piece of paper into an isosceles right triangle with a perimeter of 27 inches. If the longest side measures 11 inches, what is the area of the triangle and square inches?

Answer 1

Area = 32 square inches

Explanation:

It is given that ,

1). an isosceles right triangle with a perimeter of 27 inches

Then the base and height are equal

2). the longest side measures 11 inches

To find the smaller side

Then sum of other 2 sides = 27 - 11 = 16

Base = height = 16/2 = 8 inches

To find the are of triangle

Area = 1/2 * Base*Height

Base = 8 inches and Height = 8 inches

Area = 1/2 * 8* 8 = 32 square inches
