10 of 10 Work out the area of a rectangle with base, b = 38mm and perimeter, P =
100mm.
b

Let the height of the rectangle = h

2b + 2h = 100

2(38) + 2h = 100

2h = 100 - 76

h = 12mm

area of rectangle = base x height

= 38 x 12

= 456mm²

456mm²

Step-by-step explanation:

using formula;

b/2( P - 2b) = A

substitute values
