To find the area of a rectangle, you need both its length and width. Since only one dimension, 20mm, is provided, we cannot calculate the area without the second dimension. If you have the width, you can multiply it by 20mm to get the area in square millimeters.

What is the length of the base of a triangle with height 20mm and area 70mm squared?

If Area = 70mm2 and Height = 20mm Then Base = 7mm Using the formula Area = 0.5 x base x height, we can see that 70mm2= 0.5 x base x 20mm. Then, with simple algebra we can see that 70mm2/(0.5 x 20mm) = base Therefore, base = 7mm

How do you calculate area of 20mm steel bar?

To calculate the area of a 20mm steel bar, you can use the formula for the area of a circle, which is ( A = \pi r^2 ). First, find the radius by dividing the diameter (20mm) by 2, giving you a radius of 10mm. Then, substitute the radius into the formula: ( A = \pi (10 \text{ mm})^2 ), which results in an area of approximately 314.16 mm².
