Answer:

To find the area of the equilateral triangle, we can use the formula:

A=43​​s2

where s is the length of a side.

To find the length of a side, we can use the Pythagorean theorem on the right triangle:

s2=1.72+22

Solving for s, we get:

s=1.72+22​≈2.66

Plugging this into the formula for the area, we get:

A=43​​(2.66)2≈3.07

Therefore, the area of the equilateral triangle is about 3.07 square feet.

To find the area of the right triangle, we can use the formula:

A=21​bh

where b is the base and h is the height.

We already know that b=1.7 and h=2, so we can plug them into the formula:

A=21​(1.7)(2)=1.7

Therefore, the area of the right triangle is 1.7 square feet.

Answer:

area of a triangle = (base*relative height)/2

A = (2×1,7)/2=1.7ft²
