Answer:
Step-by-step explanation:
To find the area of rectangle, we need its dimensions.
Given - Perimeter of rectangle = 169cm, Length = 12cm
Therefore, for finding the breadth,
Perimeter of rectangle = 2(L + B)
169 = 2 (12 + B)
169 = 24 + 2B
169 - 24 = 2B
145 = 2B
145 / 2 = B
72.5 = B
Therefore, the breadth of rectangle is 72.5cm.
Area of rectangle = L x B
= 12 x 72.5
= 870
Therefore, the area of rectangle is 870sq.cm
