Question

Area and perimeter of this shape

Answer 1

Explanation:

The perimeter is all the side lengths added together so we get

Perimeter = 3 + 7.6 + 7 + 7 + 7 = 31.6

The area is the area of the triangle on top plus the area of the square on the bottom, so:

Area =
`(1)/(2) *3*7.6 + 7*7` = 11.4 + 49 = 60.4

Hope that helps!
