Question

The diagonals of a rectangle enclose an angle of measure 70° . If the perimeter of the rectangle is 360 cm, what is its area?​

Answer 1

Step-by-step explanation:

Let 7x and 11x be the length and breath of a rectangle respectively.

Perimeter =360cm

2(l+b) =360cm

7x+11x=180cm

18x=180cm

x=10cm

Length =7×10=70cm

Breath =11×10=110cm

Area of a rectangle =l×b =70×110cm² =7700cm²
