Question

The picture frame has a perimeter of 100 inches. The width is 22 inches. Calculate the missing length. Use that answer to find the area of the picture frame.

Length of frame?

Area of frame?

Answer 1

39 inches.

858 inches²

Explanation:

Length:- (if length = x)

2 ( 11 + x ) = 100

22 + 2x = 100

2x = 100 - 22

2x = 78

x = 78 ÷ 2

x = 39 inches

Area:-

Area = l × b

= 39 × 22

= 858 inches²
