Question

The lenght of a triangle is 5 centimters greater than its width . the perimeter is 58 centimeters what are demetions of the rectangles

Answer 1

Let the width be x.

Length = 5 + x

Perimeter = 58

2(l + w) = 58

2(5 + x + x) = 58

2(5 + 2x) = 58

10 + 4x = 58

4x = 48

x = 12

Hence, the length is 17 cm and the width is 12 cm.
