Question

A= 308 cm^2 b=? *A=308cm^2 P=?need help in these problems

Answer 1

Given:

Area(A) = 308 cm²

Height(b) = 14 cm

Side length = 17 cm

To find:

Base(b) and perimeter(p)

Solution:

Area of the circle formula:

$A = bh$

$308 = b \times 14$

Divide by 14 on both sides.

$\frac{308}{14} =\frac{b\times 14}{14}$

$22=b$

base = 22 cm

In parallelogram opposite sides are equal.

Perimeter = sum of all the sides

                 = 22 + 17 + 22 + 17

                 = 78 cm

Perimeter = 78 cm
