Question

the length of a rectangle is twice its breadth if we lateral triangle that drawn on its breadth length and diagonal prove that the ratio of the area is 1:4:5​

Answer 1

Step-by-step explanation:

Area of square =a2

Length of the diagonal =2a

Area of equilateral triangle with side 2a=43×(2a)2=23a2

then,

Required ratio =a23a2/2

                         =23

Hence, ratio is 3:2
