Question

if the area of ABCD is 90 square units, what is its perimeter? the width is 10

Answer 1

Answer:

Step-by-step explanation:

AREA = LENGTH x WIDTH

90 = LENGTH x 10

LENGTH = 90/10

LENGTH = 9 units

(As length is not equal to breadth , it is a rectangle)

PERIMETER = 2(L+B)

                    = 2(10+9)

                    = 38 units

Answer 2

Answer:

38 units

Step-by-step explanation:

Area of ABCD = 90 units²

Width of ABCD = 10 units

Length of ABCD = $\frac{Area}{Length}$ = (90/10) units = 9 units

(As length ≠ breadth , it is a rectangle)

Perimeter of the ABCD = 2 (l+b)

                                       = 2 (9+10) units

                                       = (2 x 19) units

                                       = 38 units
