A rectangle has a area of 12cm 2 If it is 4cm long how wide is it?
3cm
What is the area of a rectangle having a sides of 6cm long and 4cm wide?
24 square centimeters
What is the perimeter of a rectangle that is 4 cm long and 3 cm wide?
The perimeter of a rectangle is calculated by adding up the lengths of all its sides. In this case, the rectangle is 4 cm long and 3 cm wide. Therefore, the perimeter would be 2(4 cm) + 2(3 cm) = 8 cm + 6 cm = 14 cm.
A rectangle is 4cm longer than it is wide what are the demesions if the area is 8cm?
Area of a rectangle = length x width If length = L and width = W, then Area = L x W For this case, the length is 4 cm longer than the width. Therefore, L = W + 4cm Replace length in the area equation at the top with this new L value: Area = (W + 4cm) x W Area = W^2 + (4cm) x W And area is 8 cm^2 (I assume you meant to say 8cm^2 is the area) Then: 8cm^2 = W^2 +4W This is a quadratic equation (because of the w^2 value), if you solve for W using the quadratic formula (Google it), you get W = 1.464cm Therefore, the length L = W + 4cm = 1.464cm + 4cm = 5.464cm Dimensions are L = 5.464cm and W = 1.464cm
What is the dimensions of a rectangle has 20 cm area and 18 cm perimeter?
