Question

in rectangular field the length is twice of the breadth the area is 400 CM square find the length and breadth​

Answer 1

Answer:

y = 10 root 2 and x = 20 root 2

Step-by-step explanation:

Let the length and breadth of the field be x and y cm

xy = 400 square cm

x = 2y

therefore,

2y2 = 400

y2 = 200

y = root 200 = 10 root 2 cm

x = 20 root 2 cm
