Question

the ratio of two sides of a rectangle is 3:4.if it's perimeter is98cm, find the length of each diagonal of the rectangle ​

Answer 1

Let the shorter side (width) be 3*x. Then the longer side (length) is 4*x, since the sides are in the ratio 3:4. Therefore, width = 3*7 = 21cm and length = 4*7 = 28 cm. = 35 cm

Answer 2

Step-by-step explanation:

$3x + 4x = 98 \\ </p><p>7x =98 \\ x = \frac{98}{7} \\ x = 14$

3x = 3 × 14 = 42 &

4x = 4 × 14 = 56
