L = B + 5
P = 2 ( B + L ) = 150
2 ( B + B + 5 ) = 150
2 ( 2 B + 5 ) = 150
Divide both sides by 2
2 B + 5 = 75
Subtract 5 to both sides
2 B = 70
B = 70 / 2 = 35 m
L = B + 5 = 35 + 5 = 40 m
A = L ∙ B = 40 ∙ 35 = 1400 m²
P = 2 ( B + L ) = 150
2 ( B + B + 5 ) = 150
2 ( 2 B + 5 ) = 150
Divide both sides by 2
2 B + 5 = 75
Subtract 5 to both sides
2 B = 70
B = 70 / 2 = 35 m
L = B + 5 = 35 + 5 = 40 m
A = L ∙ B = 40 ∙ 35 = 1400 m²
