The base of a triangle is 18 cm and its height is 7w-1 cm. Find the expression for the triangles area
1 answer:
Answer:
Area = 9(7w -1) cm²
Step-by-step explanation:
Area of a triangle is given by the expression,
Area =
From the picture attached,
Base of the triangle = 18 cm
Height of the triangle = Vertical distance of the third vertex from the base joining other two vertices = (7w - 1)
Area =
= 9(7w - 1) square cm
Therefore, expression for the area of the given triangle will be,
Area = 9(7w -1) cm²

Base of a cube is a square, and in the given figure it's stated that the measure of each side is " x " ft
Therefore it's Area is equal to : -
Now, since it's Area is given as 1/4 ft², let's equate the Areas to find the measure of each side ~
that is ~
It's time to find the volume of cube that is ~
So, let's plug the value of side length (1/2 ft)
Volume is equal to ~
Hence, the required 1/8 or 0.125 ft³
