Question

perimeter and area.........​

Answer 1

Step-by-step explanation:

perimeter = 4l = 4 * 7 = 28 ft

Area = l² = 7² = 49 ft²

Answer 2

Answer:

$\large\boxed{\sf{Perimeter=28\;\;ft.}}$

$\large\boxed{\sf{Area=49\;\;sq.\;ft.}}$

Step-by-step explanation:

Given there a square whose side length,

• a = 7 ft.

To find the perimeter.

We know that, perimeter = 4a

Therefore, perimeter = (4×7) = 28 ft.

To find the area.

We know that, area = ${a}^{2}$

Therefore, area = (7×7) = 49 sq. ft.

Hence , the required perimeter and area of the given square are 28 ft. and 49 sq. ft. respectively.
