Answer:

The new triangle will have a perimeter of 36 cm, and an area of 18 cm2.

Step-by-step explanation:

Given that the triangle whose perimeter is 12 cm and its surface is 6 cm2, and is lengthened by a scale factor of 3 to produce a similar triangle, the perimeter and surface of the new triangle arise from the following calculation:

Perimeter = 12 x 3 = 36 cm

Area = 6 x 3 = 18 cm2

Thus, the new triangle will have a perimeter of 36 cm, and an area of 18 cm2.

Answer

length = width + 15

Area = length * width; area is 54 square feet.

Two equations are:

L = W + 15

L * W = 54

To solve, we substitute first equation into second equation:

(W + 15) * W = 54

w^2 + 15w = 54

w^2 + 15w - 54 = 0

(w+18)(w-3) = 0

w = -18 or 3

The width cannot be negative, so 3 is the width and since length is 15 more than width, length is 18:

Length = 18 feet

Width = 3 feet

Geometry question to verify it

Oksana_A [137]

Step-by-step explanation:

here's the solution,

in the given figure , sum of all angles formed with O measures 360°

because, it forms a complete angle

so,

=》mPOQ + mQOR + mROS + mSOT + mTOP = 360°

=》mPOQ + mQOR + mROS + mSOT + mTOP = (90° × 4)

=》mPOQ + mQOR + mROS + mSOT + mTOP = 4 × right angle

(cuz.. right angle = 90°)
