Hi friends please help me in this question :Book : M.L. Aggarwal Class: 9Question 1:Find the perimeter and area of the figure (i) given below in which all corners are right angles.Figure is given in tha attachment❌Spam not allowed ❌​

Answer»

Divide the figure into 2 RECTANGLES
Rectangle 1 and rectangle 2
Perimeter of rectangle 1=2(l+b)
=2(4+2)=10m
Area of rectangle 1=4X2=8m2

Perimeter of rectangle 2= 2(4+1.5)
=11m
Area of rectangle 2=4X1.5=6.5m2

Now perimeter of figure= perimeter of rectangle 1+ perimeter of rectangle 2
=10+11=21m
Area of figure = area of rectangle 1+ area of rectangle 2
=8+6.5=14.5m2
Hence SOLVED.
