Question

Length and breth of a rectangle in the ratoo of 4:3. and diagonl is 25 metets then the area ok f a rectangle

Answer 1

Let x be the common multiple.
Length = 4x
Breadth = 3x
According to Pythagoras theorem,
(4x)²+(3x)²=(25)²
16x²+9x²=625
25x²=625
x²=625/25
X =5
So,
Length = 4x = 20 cm
Breadth = 3x = 15 cm
Perimeter = 2(l×b)
= 2 (20 + 15)
= 70 cm
So, perimeter of rectangle is 70 cm.

Answer 2

perimeter of rectangle is 70cm
