Somebody please help me asap im in a very important exam and every point counts :(

Answer 1

32 inches × 24 inches

Explanation:

2(length + width) = 112

Length + width = 56

4/7 × 56 = 32

3/7 × 56 = 24

Answer 2

Hey there,
Length = 4x
Width = 3x
Perimeter = 112 inches
4x + 3x + 4x + 3x = 112 inches
14x = 112 inches
x = 112 inches / 14
= 8 inches
Length = 8 inches x 4
= 32 inches
Width = 8 inches x 3
= 24 inches

Hope this helps :))
