Answer:

Step-by-step explanation:

Remark

Here are the formulas for what you are asking for.

P = s1 + s2 + s3

Area = height * base / 2

Givens

s1 = 12.6

s2 = 6.3

s3 = 7.4

height = 4.5

base = 7.4

The area is just slightly different than it normally is. The reason is the height. It is not directly connected to the base. The construction is called the base extended.  See the givens for what that is.

Solution

<em>Perimeter</em>

P = s1 + s2 + s3                        Substitute givens into the formula

P = 12.6+6.3 + 7.4

p = 26.3

<em>Area</em>

Area = (B * H)/ 2

Area = 7.4 *4.5 / 2

Area = 16.65

Answer:

Area: 16.65m^2 (^2 means to the power of 2 exponent, or squared)

Perimeter: 26.3 m

Step-by-step explanation:

Triangle Area formula: bh/2

Plug it in: (7.4)(4.5)/2=16.65

Perimeter: Add the sides

12.6+7.4+6.3=26.3

7th Grade Math (Please help me with this question I'm confused with this one)
Vlad [161]

Answer:

To subtract a number from another number, the sign of the number (which is to be subtracted) should be changed and then this number with the changed sign, should be added to the first number

Step-by-step explanation:

(i) Evaluate (+6) – (+2)

= (+6) + (-2) (charging the sign of the number to be subtracted and then adding)

On subtracting smaller number 2 from bigger number 6; we get 6 – 2 = 4

Since, the sign of bigger number is + (positive)

= +4 or 4

Therefore, (+6) – (+2) = 4

(ii) Evaluate (+5) – (-3)

= (+5) + (+3) (charging the sign of the number to be subtracted and then adding)

We know, to add a positive (+ ve) number to a positive (+ ve) number, the numbers should be added and positive sign should be attached to the sum obtained.

= +8

Therefore, (+5) – (-3) = 8
