Question

The length of a rectangle is 4cm more than its breadth.The perimeter of the rectangle is 40cm Finds the length and breadth of it (Use linear equations) ​

Answer 1

Step-by-step explanation:

length of rectangle =x+4 cm

breadth of the rectangle =x cm

perimeter=40 cm

2(l+b)=perimeter of the rectangle

2(x+x+4)=40

2(2x+4)=40

4x+8=40

4x-32=0->linear equation

4x=32

x=8

thus;

breadth of the rectangle =x=8cm

length of the rectangle =x+4=8+4=12 cm
