Depends on the length of the sides ! The simple formula to calculate the area of a triangle is half the base times the height.

The base times the height divided by two. Imagine a right triangle is half of a rectangle. The area will also be half.

Area of a triangle = (base x height) / 2, so (9x10)/2 = 90/2 = 45.

Area of a triangle = 1/2*base*altitude in square units Area = 45 square feet

7.2 cm

Area of a triangle = (1/2) x (base) x (height) = (0.5) (45) (86) = 1,935 square meters

45 square cm

It is: 0.5*13*6 = 45 square units

45 cm2

Use the formula for the area of a triangle. The area is 1/2 x base x height.

It works out as 10 units Check: 0.5*9*10 = 45 square units

It is a triangle whose interior angles are 45, 45 and 90 degrees

1/2 base times height .5x12x7.5= uh 45... no calculator

Area of a triangle is 1/2 multiplied by base multiplied by height, hence just substitute : 1/2 X 18 X 5 = 45 feet

For example, if you have a 45-45-90 triangle. Let's say to sides are 14 and the base is 28. The perimeter would be 56. Divide the base by 2 to get 14. Then use the pythagorean theorem to find the missing side. c= 14, a= 14. and b= ?

The height or altitude of triangle: (2*45)/15 = 6cm Check: 0.5*15*6 = 45 square cm

45 sq ft

45 degrees.

Yes providing it has two 45 degrees base angles.

Yes providing it has two 45 degrees base angles.

A possibility would be A base of 8 feet and height of 5 feet. To find an area you simply multiply the length by the width, or in this case the base and height. 8x5=45.

Using Pythagoras' theorem

with a protractor. or if you don't have one, you can find it using the degrees you already have. The degrees in a triangle should always be 180. So, take the info you have, add it together, then subtract it from 180 (i.e 90+45=135. 180-135=45).
