Answer:
3.57 m and 6.6 m
Step-by-step explanation:
Area of window = area of rectangle + area of semi circle
= 2×1.4 + 22/7×7/10×7/10×1/2
2.8+0.77
= 3.57m
Perimeter of window = three sides of rectangle+Circumference of semi circle because fourth side isn't outer boundary
= 1.4+2+2+22/7×0.7
= 5.4+2.2
= 6.6 m
