Answer:
25.80
Step-by-step explanation:
Area = 315
Area = l*b
315 = 15 *b
b= 315/15
b = 21
From Right angled Triangle ,
Hypotenuse square = side square + side square
= +
= 441 + 225
= 666
apply sq root on both sides, the we get
x= 25.80
45 metres
You have to get the base to answer the question.
Do this by dividing 315 by 15 then timesing by 2
You get 42.
Do 42^2 = 1764
Do 15 ^2 = 225
Because you want the hypotenuse you add them
1764 + 225 =1989
Do the square root of 1989 which is 45 to the nearest metre
The volume is the amount of space an object takes up.
The mass is the measure of how much matter in a object.
The density is the mass <em>divided </em><em>by</em> volume.
