Find the height of a triangle with an area of 245 square inches and a base of 14 inchesn

AleksandrR [38]

Answer:

The height is 35 inches

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh

We know the area is 245 and the base is 14

245 = 1/2 (14)*h

245 = 7h

Divide each side by 7

245/7 =7h/7

35 =h

The height is 35 inches

A spider walks on the outside of a box from point A to B to C to D

Nikitich [7]

The path consists of 4 line segments. Each line segment is the hypotenuse of a different right triangle.

length of line segment AB = $\sqrt{2^{2}+5^{2} } =\sqrt{29} =5.39cm$

length of line segment BC = $\sqrt{3^{2}+4^{2} } =\sqrt{25} =5cm$

length of line segment CD = $\sqrt{3^{2}+5^{2} } =\sqrt{34} =5.83cm$

length of line segment DE $=\sqrt{2.5^{2}+3^{2} } } =\sqrt{15.25} =3.91cm$

The total length of the spider's path is about 20.13 cm.
