Question

IF THE RATIO OF LENGTH AND BREADTH IS 15 : 8 AND THE DIAGONAL IS 17 CM THEN FIND THE AREA OF THE RECTANGLE. ​

Answer 1

Length, breadth and diagonal of a rectangle form a right angle triangle.

Let diagonal be AC,

length be AB, and

breadth be BC

$AB^{2}+BC^{2}=AC^{2}\\225x^{2}+64x^{2}=289\\289x^{2}=289\\x=1$

So AB = 15 cm and BC = 8cm

Area  = $l*b=15*8=120 cm^{2}$

Answer 2

Length =15cm

Breath =8cm Diagonal =√ (length) 2 −(breath) 2

= (15) 2 +(8) 2

=17cm
