How could you use the property to compute 2x8x2 mentally

The solution is : 2,457 mm^2, is the area of the heptagon.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

The dimensions of each of the triangles in terms of their bases and heights will be;

26 mm by 27 mm

Mathematically, the area of one of the triangles will be ;

1/2 * base * height

= 1/2 * 26 * 27

= 351 mm^2

So the area of the heptagon is the sum of the areas of all of the triangles

mathematically, that would be;

351 * 7

= 2,457 mm^2

Hence, The solution is : 2,457 mm^2, is the area of the heptagon.

GCF stands for Greatest Common factor. The greatest common factor(GCF) of the two numbers 15 and 64 is 1.

What is the greatest common factor?

The greatest common factor or GCF is the common factor between two numbers.

Given to us

15 and 64

We know that the GCF is the common factor between the two numbers, therefore, in order to get the GCF of two numbers, we will write all the possible prime factors of the two numbers,

15  = 3 x 5 x 1

64 = 2 x 2 x 2 x 2 x 2 x 2 x 1

As we can see in the factors of the two numbers, the only common factor between the two numbers is 1.

Hence, the greatest common factor(GCF) of the two numbers 15 and 64 is 1.
