The height of the trapezoid is also needed to find its area which is as follows:-
Area of a trapezoid = 0.5*(sum of bases or parallel sides)*height
28cm
To find the area of a triangle, you can use the formula: Area = 0.5 * base * height. In this case, the base is 8cm and the height is 4cm. Plugging these values into the formula, the area would be 0.5 * 8cm * 4cm = 16 square centimeters.
Its base is: 44/4 = 11cm
the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2
To find the area of a rectangle, you multiply the length by the width. In this case, the length is 7 cm and the width is 4 cm. Therefore, the area of the rectangle is 7 cm x 4 cm = 28 square cm.
28cm
Area of a trapezoid = 0.5*(sum of parallel sides)*height
The ratio is: 7cm to 1cm
The area of triangle is : 8.0
Area of trapezoid: 0.5*(20+18)*4 = 76 square cm
Area = 1/2*(6+4)*height
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
To find the area of a triangle, you can use the formula: Area = 0.5 * base * height. In this case, the base is 8cm and the height is 4cm. Plugging these values into the formula, the area would be 0.5 * 8cm * 4cm = 16 square centimeters.
4cm
Its base is: 44/4 = 11cm
What you do is you multiply the base by the height then you must half your answer. Eg: A triangle with a base of 2 cm and a height of 4cm, you would do 2x4=8 then half your answer to get 4cm squared.
Area = 0.5*4*5 = 10 square cm
