Find the perimeter and area of a rectangle of:(b) L = 14.5 km, B = 7 k

1.	Find the perimeter and area of a rectangle of:(b) L = 14.5 km, B = 7 km(a) L = 16.5 cm, B = 12 cm(c) L = 21 cm, B = 13.7 cm
Answer» Answer: b. perimeter = sum of all sides. so. 14.5 + 7 km = 21.5 area of TRIANGLE = length×breadth so. 14.5 × 7= 101.5 km a. perimeter= 16.5 + 12 = 28.5cm area= 16.5 × 12 =198cm2 c. perimeter = 21 + 13.7 = 34.7cm area = 21× 13.7=287.7cm2 Step-by-step EXPLANATION: It will HELP you a lot.. please add me as a brainlist

Find the perimeter and area of a rectangle of:(b) L = 14.5 km, B = 7 km(a) L = 16.5 cm, B = 12 cm(c) L = 21 cm, B = 13.7 cm

Answer»

Answer:

b. perimeter = sum of all sides.

so. 14.5 + 7 km = 21.5

area of TRIANGLE = length×breadth

so. 14.5 × 7= 101.5 km

a. perimeter= 16.5 + 12 = 28.5cm

area= 16.5 × 12 =198cm2

c. perimeter = 21 + 13.7 = 34.7cm

area = 21× 13.7=287.7cm2
