Answer:
cannot complete it now, I gotta go!!!
Step-by-step explanation:
4.
perimeter P=100cm
length l = 35 cm
breadth b = ????
P = 2l + 2b = 2(l+b) therefore 2(l+b) = 100
l+b=50 you know that l = 35
b = 50-35 = 15cm
area is l*b=35*15=525 cm²
5.
ls = square side
lr = length rectangle
br = breadth rectangle
Area square = Area rectangle
ls*ls = lr*br we know that ls = 60 m and that lr=90
so we can rewrite is as 60*60 = 90 * br
3600 = 90*br
br = 3600/90 = 40m
6.
length = 40cm, breadth = 22cm
Perimeter = 2(40+22) = 124 cm
a square sides are all equal so
side = 124/4 = 31cm
area of the square = 31*31 = 31²= 961 cm²
area of the rectangle = 40*22= 880 cm²
square has a wider area
