Question

the length of a rectangle is 5xm more than its breadth. if the perimeter of a rectangle is 38cm find its area (in cm²)​

Answer 1

Answer:

84 sqcm

Step-by-step explanation:

given,

length of a rectangle is 5cm more than its breadth,

i.e,l=b+5,

perimeter of a rectangle is 38cm,

that means,2(l+b)=38,

=>l+b=19,

=>5+b+b=19,

=>2b=14,

=>b=7cm & l=12cm

therefore,

Area of rectangle is l*b=12*7=84sqcm.
