Question

what is the perimeter of 14 square units​

Answer 1

Answer:

Side of one square =1 unit

Area of one square =1×1=1 sq. unit

(A) Area of 18 squares=18 sq. units

Perimeter =2(6+3)=18 units

(B) Area of 18 squares =18 sq. units

Perimeter =2(9+2)=22 units

(C) Area of 16 squares =16 sq. units

Perimeter =2(8+2)=20 units

(D) Area of 20 squares =20sq. units

Perimeter =2(5+4)=18 units.

Answer 2

Length (l) * breath (b) = area = 12

2.l + 2.b = perimeter

24/b + 2b = 14

2b^2 -14b +24 =0 or b^2 -7b + 12 = 0

Solving b=4 or b =3

Therefore l = 3 or l = 4
