20 in
Area of a triangle = 1/2*base*height Area = 14 square inches
Area = Base x Height therefore.... 7in x 4in = 28in =area
3+3+7+7 = 20 inches
5ft. 7in.
His height is 174cm or 5ft 7in
bh, or base x height. For example: The base of a square is 7in. The height is 9in. The Surface Area would be 63in. For the surface area of a triangle, the formula is bh/2. base times height divided by two. ok, a square would have all four sides the same, just saying.
i was 5ft 7in when i was 14
Just multiply the three dimensions together10in x 4in x 7in = 280in3
5ft 7in
The difference in height between a 6ft 4in man and a 5ft 2in woman is 14 inches (6ft 4in - 5ft 2in = 14in). To see their complete head to toe image in a plane mirror, the mirror should be at least half the difference in height away from the person. Therefore, the mirror should be at least 7 inches longer for the man (14in/2 = 7in) than for the woman.
I'm pretty sure it's 5ft 7in, somewhere around there.
