Question

which of the following is a true statement about the rectangle below? a. perimeter = 28 m² b. perimeter = 40 m c. area = 28 m d. area = 40 m² 10 meters 4 meters

Explanation:

Step1: Recall perimeter formula

The perimeter formula for a rectangle is $P = 2(l + w)$, where $l$ is the length and $w$ is the width. Given $l = 10$ m and $w = 4$ m, then $P=2(10 + 4)$.
$P=2\times14=28$ m.

Step2: Recall area formula

The area formula for a rectangle is $A=l\times w$. Given $l = 10$ m and $w = 4$ m, then $A = 10\times4=40$ m².

Answer:

D. Area = 40 m²
