Question

Work out the area of a rectangle with base, b= 14mm and perimeter, P= 38mm

Answer 1

Answer:

Step-by-step explanation:

Area of rectangle = length × breadth

Base =14mm

Perimeter =38mm

So, lenght = (perimeter/2) - breadth

= (38/2) - 14

= 19 - 14 = 5

So, length is 5 mm

Area = (l×b) = 5×14=70mm

Therefore the area of the rectangle is 70 mm
