(a)The area of a rectangular field is 7392 .
If the length of the field is 96 , what is its width?

(b)The perimeter of a rectangular painting is 372 .
If the width of the painting is 88 , what is its length?

W = 77

L = 98

Step-by-step explanation:

Question a:

Area of a rectangular field = 7392

Length L = 96

Width w = ?

Area of a rectangle = L x W

7392 = 96 x W

Divide both sides by 96

7392/96 = 96/96 x w

77 = w

W = 77

Question b:

Perimeter of a rectangular painting = 372

Width = 88

Length = ?

Perimeter of a rectangle =

2(L + w)

372 = 2(L + 88)

Distribute 2 into (L + 88)

We have

372 = 2 x L + 2 x 88

372 = 2L + 176

Subtract 176 from both sides

372 - 176 = 2L + 176 - 176

196 = 2L

Divide both sides by 2

196/2 = 2L/2

98 = L

L = 98
