The area of a rectangle is 240 in squared. the ratio of the length to the width is 5 : 3. find the length and the width.

Hey user!!

your answer is here...

given the ratio between the Length and breadth (width) of the rectangle is 5 : 3

let the Length and breadth of the rectangle be 5x and 3x approximately.

area of the rectangle = 240in²

therefore l × b = 240in²

==> 5x × 3x = 240in²

==> 15x² = 240in²

==> x² = 240/15

==> x² = 16

==> x = √16

==> x = 4in

hence, length of the rectangle = 5x = 5 × 4 = 20in

breadth of the rectangle = 3x = 3 × 4 = 12in

cheers!!

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
