The altitude of an equilateral triangle bisects the base. So, if the sides of the triangle were l cm, the altitude forms a right angled triangle with sides h, l/2 and hypotenuse l cm. Then, by Pythagoras, h2 = 3l2 / 4 so that h = l*sqrt(3)/2 and then area = l*h/2 = l*[l*sqrt(3)/2]/2 =l2*sqrt(3)/4
If P = 40 then L + W = 20. The only combination which gives A = 100 is where L and W are both 10, ie the figure is a square of side 10 cm.

Volume = H x L x W 40 = H x 4 x 2 40 = H x 8 40/8 = (H x 8)/8 5 = H
To find the height of the container, you can use the formula for volume of a rectangular prism, which is given by V = l * w * h. Since the volume is 40 cm3, the length is 4 cm and the width is 2 cm, you can rearrange the formula to solve for height: h = V / (l * w) = 40 / (4 * 2) = 40 / 8 = 5 cm. Thus, the height of the container is 5 cm.
To find the width of a rectangle, multiply the lenght by 2 and subtract it from the perimeter. Once this is done you are left with the two width sides of the rectangle. To find the width divide this number by 2 and you have your answer. For exaple: P= 120 cm L= 40 cm L* 2 = 80 120 - 80 = 40 40/2 = 20 W=20

A rectangle cannot have an area of 40 cm since the units for area are cm2. The following are some examples of rectangles with an area of 40 cm2: 10cm * 4 cm 1 000 cm * 0.04 cm 10*sqrt(2) cm * 2*sqrt(2) cm 10*pi cm x 4/pi cm Basically, take any number, L cm, as length and let 40/L cm be the breadth.
XL is 40, L is 50, LX is 60, LXX is 70, LXXX is 80
l*w*h = 40*40*40 = ft^3
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
