p = 75+75+45+45=240cm
a = 75 x 45 = 3375cm
33.08 is 75% of 45
Perimeter = 2(l+w) => 2(75+25) => 200 metres Area = (l*w) => (75*25) => 1875 square metres.

75%
P = 2L + 2WP/2 = L + WW = P/2 - LW = 150/2 - 45 = 75 - 45 = 30A = LW = (45)(30) = 1350 unit2
we know,perimeter of rectangle = 2 * ( l+b) perimeter= 2 *(45+30) = 2 * 75 =150 cm
Perimeter of rectangle = 2 *(l+b) =2 *(45+30)= 2 * 75 =150 cm
To find the area of the Norman window, you need to divide the perimeter by 2 to get the width of the rectangle, which is 22.5 feet. The radius of the semicircle is half of the rectangle's width, so it's 11.25 feet. The area of the rectangle is 11.25 * 22.5 = 253.13 square feet, and the area of the semicircle is 0.5 * pi * 11.25^2 = 198.93 square feet. So, the total area of the window is 253.13 + 198.93 = 452.06 square feet.
Need more information, like shape...
There's not enough information here to figure that out. If it was a square, we'd know it was 15 x 15 and the perimeter would be 60. But there are four possible whole number rectangles with differing perimeters. 250 x 1, perimeter 502 75 x 3, perimeter 156 45 x 5, perimeter 100 25 x 9, perimeter 68
The perimeter is 150 cm. The formula is twice the sum of (width plus length). P = 2(w+l) = 2(30+45)= 2(75)=150150 cm
Perimeter = 174cm (75 +75 +12 +12)
75 millimeters=7.5 centimeters
(1/2)base*height = .5(10)(15) = 75
1 m = 100 cm so 1.1 m = 110 cm. Therefore: 45 + 75 + 110 = 230 cm = 2.3 m
