The area of a triangle is 494 cm. sq. if base is 38 cm, find the height.

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

Using the given information we can solve for the height:

494 = 1/2 x 38 x height

Divide both sides by 38:

13 = 1/2 x height

Multiply each side by 2:

26 = height.

The height is 26 cm.

answer:

a=9

step-by-step explanation: lmk if you need a explanation

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
