Find the length of the diagonal of a rectangle whose length and width are 35cm and 12cm respectively?
Easiest thing to do here would be to draw a diagram and label the sides with their lengths and draw a line for the diagonal. You can see the diagonal forms part of a right-angled triangle, with its shorter lengths 35 cm and 12 cm. So using Pythagoras's Theorem, x2 = 352 + 122 = 1369 x = square root of 1369 = 37 cm.
What is the perimeter of 7cm by 6cm?
Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^
What is the perimeter of a rectangle 12cm by 5cm?
34cm
What is the length and width of a rectangle if the area is 108 square centimeters?
Without any further information regarding the rectangle, any two numbers that multiply to get 108 will suffice: 1cm x 108cm 2cm x 58cm 3cm x 36cm 4cm x 27cm 6cm x 18cm 9cm x 12cm Plus if the sides are allowed to not be whole numbers, there are many, many more. For example: 10cm x 10.8cm 5cm x 21.6cm
Perimeter of a rectangle 12cm x 8cm?
12+12=24 8+8= +16 The perimeter =40cm2
