Question

Mario is looking for the dimensions of the rectangular garden that has an area of 14m² and a perimeter or 18 meters

Answer 1

Answer:

L×B=14 .....(1)

2(L+B)=18

L+B=9 ..... (2)

L=9-B

put this value of L in (1)

(9-B)×B = 14

9B - B^2 - 14 = 0

B^2-9B +14=0

B^2 -2B -7B +14=0

B(B-2)-7(B-2)=0

(B-2)(B-7)=0

B=2 and B=7

putting these values of B in (1) or (2) you can get values of L

if B=2, then L=7 Ans
