The answer would be C
7/9 = 0.77777778
if the ratio of sides is 2:3, the ratio of the perimeters will be the same
2 16
------- = ---------
3 P
Using cross product 2*P = 3*16
2P = 48
P = 24 inches
Answer:
SA = 144 ft²
Step-by-step explanation:
SA = 1/2(9)(6)(4) + (6 x 6) = 144 ft²
Perimeter is 54 cm. length is 15 cm so 2 x 15 =30 . so we are left with 54-30 =24 cm.so 2 x width =24 cm . so the width is 12 cm
