(c) With the same area, the carpenter is required to make a rectangular table such that its length is four times its breadth. Find the dimensions of the surface of the table.

Answer 1

Answer:

area = side×side

dimensions = 300cm×300cm

area of rectangle = length × breadth

4B=L

L×b=90000

4B×B=90000

4B² = 90000

B= root 90000/root4

B= 300/2

B= 150 cm

L=4×150= 600cm
