Question

1. the rectangle shown has an area of 56 square meters. what is its missing side - length? find the perimeter.

Explanation:

Step1: Find the missing side length

We know the area formula for a rectangle is $A = l\times w$. Given $A = 56$ square - meters and one side $w = 7$ m. So, $l=\frac{A}{w}$. Substituting the values, we get $l=\frac{56}{7}=8$ m.

Step2: Calculate the perimeter

The perimeter formula for a rectangle is $P = 2(l + w)$. Substituting $l = 8$ m and $w = 7$ m, we have $P=2(8 + 7)=2\times15 = 30$ m.

Answer:

Length: 8 m
Perimeter: 30 m
