1. find the area of the shaded part region. assume all figures are squares
first figure out the area between the two squares
the area of the middle triangle is half the area of the smaller square
=
2. find The area of the shaded part region
Area of two triangle = 2 × 1/2 × b×h
= 4x 4 = 16cm²
Area of circle
Area of shaded region = Area of tn code - Area of triangle
= (50•24 - 32)cm²
=
3. A grass lawn is 85 m long and 60 m wide. A rectangular flower plot is found in the middle y the lawn which measure 25 m by 20m. what is the area covered by grass?
The area of grass
The area of grass lawn
The area of flower pot
So, the area covered by grass
= 5100 - 500
=
4. two square are positioned as shown. there is 4 dm margin between the small and large square. what is the area of the shaded part
Suppose that the side lenght of a large square is a, and that of a small square is b
a = 18dm
b = a - 4 = 14dm
S shade = S large - S small
=
5. the diagram below shows the dimensions of Mrs Lee s swimming pool. A cover is needed for the pool what is the area of the cover
