Answer:
20,184 cm²
Step-by-step explanation:
2(8x + 3x) = 640
11x = 320
x = 320/11 ≈ 29
l = 8 × 29 = 232
w = 3 × 29 = 87
A = lw = 232×87
A ≈ 20,184 cm²

Answer:
20184 cm²
Step-by-step explanation:
let the common factor of ratio be x
area = 2(8x + 3x) = 640
11x = 320
x = 320/11 = 29
length = 8 x 29 = 232
breath = 3 x 29 = 87
Area = lxb = 232x87
Area = 20184 cm²
