Here is my question again:

Step-by-step explanation:

A garden is in a shape of an equilateral triangle with side 4 ft.

The objective is to find the area of the garden.

The formula to find the area of the triangle is, A= 1/2• b • h

Here, b represents the side of the triangle and h represents and h represents the height of the triangle.

The height of an equilateral triangle can be calculated by,

H = /3/2 • b

= /3/2 • 4

=

Now substitute the value of b and h in the formula of area of triangle.

A = 1/2 • 4 •

=

ft²

Step-by-step explanation:

Base of the triangle is:

Height of the triangle:

Area is:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
