What is the are for a rectangle of 13cm and 7cm
The area is approx 24.25 cm2.
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
39 cm
Area = 1/2*5*7 = 17.5 square cm
Area of Triangle = 1/2 base x height 28 = 4 x height height = 7 cms
In an acute triangle, if the largest angle measures 89.99 degrees, and two of the sides are 7 and 13 centimetres, then the remaining side will be 10.96 centimetres. Other lengths are possible, but without knowing the magnitude of at least one of the angles, it is impossible to list them all here. the answer is 218 cm. you have to take 7 times 7 =49,then you take 13 times 13 =169,then you add the two figures together to get the answer 218 cm

A triangle with side a: 7, side b: 7, and side c: 7 cm has an area of 21.22 square cm.
The area of a triangle is calculated by multiplying the base by the height and dividing the result by 2. In this case, the area of the triangle would be (5 cm x 7 cm) / 2 = 35 cm².
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
39 cm
Yes. The triangle with sides 7 cm, 8 cm, 13 cm is obtuse (the angle opposite the side of 13 cm is 120o) and scalene as none of the sides are equal.
Area = 1/2*5*7 = 17.5 square cm
10.95 cm
Area = 0.5*12*7 = 42 square cm
Area of isosceles triangle: 0.5*5*7 = 17.5 square cm
Yes.eg The triangle with sides 7 cm, 8 cm, 13 cm is both obtuse (angle opposite side of 13 cm is 120o) and scalene (none of the sides are equal).
Area of Triangle = 1/2 base x height 28 = 4 x height height = 7 cms
