Q.17. (b) Find the perimeter and area of the figure (ii) given below in which all corners are right angles.

Dear student,


we know, Area of rectangle=L×BArea of region I (rectangle)=7×3=21 cm2Area of region II (rectangle)=8×2=16 cm2Area of region III (rectangle)=7×2=14 cm2Thus the Area of fig=Area of region I +Area of region II+Area of region III=21+16+14cm2 Area of fig=51 cm2we know, Perimeter of rectangle=2L+BNow, Perimeter of region I=27+3=2×10=20 cmPerimeter of region II=28+2=2×10=20 cmPerimeter of region III=27+2=2×9=18 cmThus, Perimeter of fig= Perimeter of region I+ Perimeter of region II+ Perimeter of region III=20+20+18cm Perimeter of fig=58 cm
