Answer 1

9514 1404 393

Answer:

• perimeter: 121 m
• area: 399 m²

Explanation:

The perimeter is the sum of the side lengths. Here, the bottom side is broken into two parts, so that side length is the sum of the parts. The area is given by the formula for the area of a triangle.

perimeter = 24 m +40 m + 37 m + 20 m = 121 m

area = 1/2bh = 1/2(20 m +37 m)(14 m) = 399 m²
