The lengths of the sides of a rectangle are in the ratio of 4: 7. if the longer side is 31.5 in, find the width, the perimeter, and the area of this rectangle.

We are given lengths of sides of the rectangle = 4:7.

Longer side is 31.5 inches.

Let us assume width be x.

Setting proportion, we get

On cross multiplication, we get

7x = 31.5 × 4

7x = 126.

Dividing both sides by 7, we get

7x/7 = 126/7

x = 18.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
