Question

the measure of two adjacent sides of a rectangle are in the ratio 11 : 10 if the area is 3960 m square then find its length and breadth

Answer 1

Let the common ratio be x.so sides are
11x and 10 x .
now area of rectangle=l×b=11x×10x=110x^2
now 110x^2=3960
x^2=3960÷110=36
x=6
11x=11×6=66
10x=10×6=6660
length of rectangle =66m
breadth of rectangle =60m

Answer 2

Answer:

Hope it's helpful to you

Step-by-step explanation:

The common ratio = ×

=11× and 10×

Area of rectangle = l×b =11× multiply 10×

=110 × 2

110 ×2 = 3960

×2=3960÷110

=36

×=6

11×=11×6=66

10×10×6=6660

Length of rectangle =66 m

Breadth of rectangle =60 m
