The given figures is of square pryamid with the square base

Area of square = side x side

In the given figure, the length of the base of the square = 8in

Area of base of square = 8 x 8

Area of base of square = 64 in²

The lateral area of a right pyramid can be calculated by

multiplying half of the perimeter of the base by the slant

height.

Lateral surface area = 1/2 x Perimeter of the base x slant height

Since, the base of the pryamid is square so, the perimeter for the base pf pryamid = 4side

Perimeter = 4 x side

Perimeter = 4 x 8

Perimeter of the base of pryamid is 32 in

Slant height is given as 7in

Lateral surface area = 1/2 x 7 x 32

LAteral surface area = 7 x 16

Lateral surface area = 112 in²

The total surface area can be calculated by adding base are to the lateral surface area

Total surface area = Lateral surface area + Base area

Total surface area = 112 + 64

Total surface area = 176 in²

Answer:

Area of base of square = 64 in²
