Calculating Area, Perimeter, and Diagonal Length of a Rectangle

​
length L
10
breadth B
4.3
​
area of rectangle =
L × B = 10 × 4.3 = 43.
​
perimeter of rectangle =
2(L + B) = 2(10 + 4.3) = 28.6
​
diagonal length =

Mensuration formulas are applied to calculate the area, perimeter, and diagonal length of a rectangle on the basis of its length and breadth.
