The rectangle shown has a perimeter of 58 cm and the given area. its length is 8 more than twice its width. write and solve a system of equations to find the dimensions of the rectangle. the area is 154cm squared

The length of the rectangle is 22 cm and width is 7 cm.

Step-by-step explanation:

Let the width of the rectangle be 'w'.

Given:

Perimeter (P) = 58 cm

Area of the rectangle (A) = 154 cm²

As per question:

Length = 8 more than twice its width

Now, perimeter is given as:

Now, we have to solve the given system of equations.

For that, we plug in 'L' from equation 1 to equation 2. This gives,

Therefore, the length of the rectangle is 22 cm and width is 7 cm.

Area = Length × Width = 22 × 7 = 154 cm².

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
