Find the surface area of the pyramid. The side lengths of the base are equal.

Your answer will be

576.66615 but if rounded it will be 576.67

Step-by-step explanation: Hope I helped

552cm squared

Step-by-step explanation:

The first step is to find one of the surface areas of the triangles.

(12*17*0.5)

102

Now that we have one of them, we need to find what the four of them together is equal to.

(102*4) or 102 + 102 + 102 + 102

408

The next time is to find what the square is equal to.

(12*12)

144

The last step is to add the four triangles and the squares surface areas together.

408+144

552

The surface area of the shape is going to be 552cm^2

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
